Agriculture
–
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of human civilization. The study of agriculture is known as agricultural science, the history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology, genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. Agricultural food production and water management are increasingly becoming global issues that are fostering debate on a number of fronts, the major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include cereals, vegetables, fruits, oils, meats, fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo, other useful materials are also produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental products such as cut flowers and nursery plants. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, field, Agriculture usually refers to human activities, although it is also observed in certain species of ant, termite and ambrosia beetle. To practice agriculture means to use resources to produce commodities which maintain life, including food, fiber, forest products, horticultural crops. This definition includes arable farming or agronomy, and horticulture, all terms for the growing of plants, even then, it is acknowledged that there is a large amount of knowledge transfer and overlap between silviculture and agriculture. In traditional farming, the two are often combined even on small landholdings, leading to the term agroforestry, Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin, wild grains were collected and eaten from at least 105,000 years ago. Pigs were domesticated in Mesopotamia around 15,000 years ago, rice was domesticated in China between 13,500 and 8,200 years ago, followed by mung, soy and azuki beans. Sheep were domesticated in Mesopotamia between 13,000 and 11,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Cattle were domesticated from the aurochs in the areas of modern Turkey. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca, llamas, alpacas, sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago, cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia at an unknown time

Landscape
–
A landscape is the visible features of an area of land, its landforms and how they integrate with natural or man-made features. The character of a landscape helps define the self-image of the people who inhabit it and it is the dynamic backdrop to people’s lives. Landscape can be as varied as farmland, a landscape park, the activity of modifying the visible features of an area of land is referred to as landscaping. There are several definitions of what constitutes a landscape, depending on context, the term landscape emerged around the turn of the sixteenth century to denote a painting whose primary subject matter was natural scenery. Land may be taken in its sense of something to people belong. The suffix ‑scape is equivalent to the more common English suffix ‑ship, the roots of ‑ship are etymologically akin to Old English sceppan or scyppan, meaning to shape. The suffix ‑schaft is related to the verb schaffen, so that ‑ship, the word landscape, first recorded in 1598, was borrowed from a Dutch painters term. An example of this usage can be found as early as 1662 in the Book of Common Prayer, Could we but climb where Moses stood. Setting, In works of narrative, it includes the moment in time and geographic location in which a story takes place. Picturesque, The word literally means in the manner of a picture, fit to be made into a picture, and used as early as 1703, gilpin’s Essay on Prints defined picturesque as a term expressive of that peculiar kind of beauty, which is agreeable in a picture. A view, A sight or prospect of some landscape or extended scene, wilderness, An uncultivated, uninhabited, and inhospitable region. Cityscape, The urban equivalent of a landscape, in the visual arts a cityscape is an artistic representation, such as a painting, drawing, print or photograph, of the physical aspects of a city or urban area. Seascape, A photograph, painting, or other work of art depicts the sea. Geomorphology is the study of the origin and evolution of topographic and bathymetric features created by physical or chemical processes operating at or near Earths surface. Geomorphology is practiced within physical geography, geology, geodesy, engineering geology, archaeology and this broad base of interests contributes to many research styles and interests within the field. The surface of Earth is modified by a combination of processes that sculpt landscapes, and geologic processes that cause tectonic uplift and subsidence. Many of these factors are strongly mediated by climate, the Earth surface and its topography therefore are an intersection of climatic, hydrologic, and biologic action with geologic processes.

Revegetation
–
Revegetation is the process of replanting and rebuilding the soil of disturbed land. Originally the process was one of applying seed and fertilizer to disturbed lands. The fibrous root network of grasses is useful for erosion control. Establishing long-term plant communities requires forethought as to appropriate species for the climate, size of stock required, the motivations behind revegetation are diverse, answering needs that are both technical and aesthetic, but it is usually erosion prevention that is the primary reason. Revegetation also aids protection of engineered grades and other earthworks, Revegetation is often used to join up patches of natural habitat that have been lost, and can be a very important tool in places where much of the natural vegetation has been cleared. Revegetation plans therefore need to consider how the sites are connected with existing habitat patches. Revegetation in agricultural areas can support breeding populations, but often it supports more common species. Mine reclamation may involve soil amendment, replacement, or creation, in some cases, the native soil may be removed prior to construction and replaced with fill for the duration of the work. After construction is completed, the fill is again removed and replaced with the native soil for revegetation. Mycorrhizae, symbiotic fungal-plant communities, are important to the success of revegetation efforts, most woody plant species need these root-fungi communities to thrive, and nursery or greenhouse transplants may not have sufficient or correct mycorrhizae for good survival. Regional differences in ectomycorrhizal fungi may also affect the success of revegetation, rewilding Tubestock The Lorax Revegetation in Alaska, Usibelli, seeds & topsoil, and mycorrhizae, Dot Helm.

Consolidation (soil)
–
Consolidation is a process by which soils decrease in volume. According to Karl von Terzaghi consolidation is any process which involves a decrease in water content of saturated soil without replacement of water by air, in general it is the process in which reduction in volume takes place by expulsion of water under long term static loads. It occurs when stress is applied to a soil causes the soil particles to pack together more tightly. When this occurs in a soil that is saturated with water, water will be squeezed out of the soil, the magnitude of consolidation can be predicted by many different methods. In the Classical Method, developed by Terzaghi, soils are tested with an oedometer test to determine their compression index and this can be used to predict the amount of consolidation. When stress is removed from a soil, the soil will rebound. If the stress is reapplied, the soil will consolidate again along a recompression curve, the soil which had its load removed is considered to be overconsolidated. This is the case for soils which have previously had glaciers on them, the highest stress that it has been subjected to is termed the preconsolidation stress. The over consolidation ratio or OCR is defined as the highest stress experienced divided by the current stress, a soil which is currently experiencing its highest stress is said to be normally consolidated and to have an OCR of one. A soil could be considered underconsolidated immediately after a new load is applied, the process of consolidation is often explained with an idealized system composed of a spring, a container with a hole in its cover, and water. In this system, the spring represents the compressibility or the structure of the soil itself, the container is completely filled with water, and the hole is closed. A load is applied onto the cover, while the hole is still unopened, at this stage, only the water resists the applied load. As soon as the hole is opened, water starts to drain out through the hole, after some time, the drainage of water no longer occurs. Now, the spring alone resists the applied load and this method assumes consolidation occurs in only one-dimension. Laboratory data is used to construct a plot of strain or void ratio versus effective stress where the stress axis is on a logarithmic scale. The plots slope is the index or recompression index. The equation for consolidation settlement of a consolidated soil can then be determined to be. E0 is the void ratio

Dryland farming
–
Dryland farming and dry farming are agricultural techniques for non-irrigated cultivation of crops. Dryland farming is associated with drylands - dry areas characterized by a wet season followed by a warm dry season. Dryland farming was introduced to southern Russia and Ukraine by Ukrainian Mennonites under the influence of Johann Cornies, in Australia, it is widely practiced in all states but the Northern Territory. Dry farming may be practiced in areas that have significant annual rainfall during a wet season, Crops are cultivated during the subsequent dry season, using practices that make use of the stored moisture in the soil. California, Colorado and Oregon, in the United States, are three states where dry farming is practiced for a variety of crops, Dryland farmed crops may include winter wheat, corn, beans, Sunflowers or even watermelon. Successful dryland farming is possible with as little as 9 inches of precipitation a year, native American tribes in the arid Southwest survived for hundreds of years on dryland farming in areas with less than 10 inches of rain. The choice of crop is influenced by the timing of the predominant rainfall in relation to the seasons. For example, winter wheat is more suited to regions with higher winter rainfall areas with summer wet seasons may be more suited to summer growing crops such as sorghum. Dry farmed crops may include grapes, tomatoes, pumpkins, beans and these crops grow using the winter water stored in the soil, rather than depending on rainfall during the growing season. Dryland farming has evolved as a set of techniques and management practices used by farmers to adapt to the presence or lack of moisture in a given crop cycle. In marginal regions, a farmer should be able to survive occasional crop failures. Survival as a dryland farmer requires careful husbandry of the moisture available for the crop, Dryland farming involves the constant assessing of the amount of moisture present or lacking for any given crop cycle and planning accordingly. Dryland farmers know that to be successful they have to be aggressive during the good years in order to offset the dry years. The fact that a period must be included in the crop rotation means that fields cannot always be protected by a cover crop. Some of the theories of dryland farming developed in the late 19th and early 20th centuries claimed to be scientific but were in reality pseudoscientific, Dry farming depends on making the best use of the bank of soil moisture that was created by winter rainfall. Some dry farming practices include, Wider than normal spacing, to provide a bank of moisture for each plant. Strict weed control, to ensure that weeds do not consume soil moisture needed by the cultivated plants, cultivation of soil to produce a dust mulch, thought to prevent the loss of water through capillary action. This practice is controversial, and is not universally advocated, selection of crops and cultivars suited for dry farming practices

Livestock
–
Livestock are domesticated animals raised in an agricultural setting to produce commodities such as food, fiber, and labor. The term is used to refer solely to those raised for food. In recent years, some organizations have also raised livestock to promote the survival of rare breeds, animal husbandry practices have varied widely across cultures and time periods. Originally, livestock were not confined by fences or enclosures, but these practices have largely shifted to intensive animal farming and these practices increase yield of the various commercial outputs, but have led to increased concerns about animal welfare and environmental impact. Livestock production continues to play an economic and cultural role in numerous rural communities. Livestock as a word was first used between 1650 and 1660, as a merger between the live and stock. Older English sources, such as the King James Version of the Bible, the word cattle is derived from Old North French catel, which meant all kinds of movable personal property, including livestock, which was differentiated from immovable real estate. In later English, sometimes smaller livestock such as chickens and pigs were referred to as small cattle, today, the modern meaning of cattle, without a modifier, usually refers to domesticated bovines, but sometimes livestock refers only to this subgroup. Legal definition United States federal legislation sometimes more narrowly defines the term to make specified agricultural commodities either eligible or ineligible for a program or activity, for example, the Livestock Mandatory Reporting Act of 1999 defines livestock only as cattle, swine, and sheep. Animal-rearing originated during the transition to settled farming communities from hunter-gatherer lifestyles. Animals are domesticated when their breeding and living conditions are controlled by humans, over time, the collective behaviour, lifecycle and physiology of livestock have changed radically. Many modern farm animals are unsuited to life in the wild, dogs were domesticated in East Asia about 15,000 years ago. Goats and sheep were domesticated around 8000 BC in Asia, swine or pigs were domesticated by 7000 BC in the Middle East and China. The earliest evidence of horse domestication dates to around 4000 BC, the term livestock is nebulous and may be defined narrowly or broadly. Broadly, livestock refers to any breed or population of animal kept by humans for a useful and this can mean domestic animals, semidomestic animals, or captive wild animals. Semidomesticated refers to animals which are only lightly domesticated or of disputed status and these populations may also be in the process of domestication. Some people may use the term livestock to refer to only used for red meat. Livestock are used by humans for a variety of purposes, many of which have an economic value, Livestock products include, Meat A useful form of dietary protein and energy, meat is the edible tissue of the animal carcass

Dust
–
Dust is fine particles of matter. It generally consists of particles in the atmosphere that come from sources such as soil, dust lifted by weather, volcanic eruptions. House dust mites are present indoors wherever humans live, positive tests for dust mite allergies are extremely common among people with asthma. Dust mites are microscopic arachnids whose primary food is dead skin cells. They and their feces and other allergens they produce are major constituents of house dust and they are generally found on the floor and other surfaces until disturbed. It could take somewhere between twenty minutes and two hours for dust mites to settle back down out of the air, Dust mites are a nesting species that prefers a dark, warm, and humid climate. They flourish in mattresses, bedding, upholstered furniture, and carpets and their feces include enzymes that are released upon contact with a moist surface, which can happen when a person inhales, and these enzymes can kill cells within the human body. House dust mites did not become a problem until humans began to use textiles, such as western style blankets and clothing. Atmospheric or wind-borne dust, also known as aeolian dust, comes from arid and dry regions where high velocity winds are able to remove mostly silt-sized material, Dust in the atmosphere is produced by saltation and sandblasting of sand-sized grains, and it is transported through the troposphere. This airborne dust is considered an aerosol and once in the atmosphere, saharan dust in particular can be transported and deposited as far as the Caribbean and the Amazon basin, and may affect air temperatures, cause ocean cooling, and alter rainfall amounts. Dust in the Middle East has been a historic phenomenon, recently, because of climate change and the escalating process of desertification, the problem has worsened dramatically. As a multi-factor phenomenon, there is not yet a consensus on the sources or potential solutions to the problem. In Iran, the dust is already affecting more than 5 million people directly, in the province of Khuzestan it has led to the severe reduction of air quality. The amount of pollutants in the air has surpassed more than 50 times the normal level several times in a year, recently, initiatives such as Project-Dust have been established to directly study the Middle Eastern dust. Dust kicked up by vehicles traveling on roads may make up 33% of air pollution, road dust consists of deposits of vehicle exhausts and industrial exhausts, particles from tire and brake wear, dust from paved roads or potholes, and dust from construction sites. Road dust is a significant source contributing to the generation and release of particulate matter into the atmosphere. Control of road dust is a significant challenge in urban areas, road dust may be suppressed by mechanical methods like street sweeper vehicles equipped with vacuum cleaners, vegetable oil sprays, or with water sprayers. Improvements in automotive engineering have reduced the amount of PM10s produced by road traffic, coal dust is responsible for the lung disease known as pneumoconiosis, including black lung disease that occurs among coal miners

Sewage
–
Sewage is a water-carried waste, in solution or suspension, that is intended to be removed from a community. Also known as domestic or municipal wastewater, it is characterized by volume or rate of flow, physical condition, chemical and toxic constituents and it consists mostly of greywater, blackwater, soaps and detergents, and toilet paper. Whether it also contains surface runoff depends on the design of sewer system, all sewage ends up back in the environment, by any of several routes. A basic distinction in its route is whether it undergoes sewage treatment to mitigate its effect on the environment before arriving there, Sewage usually travels from a buildings plumbing either into a sewer, which will carry it elsewhere, or into an onsite sewage facility. Whether it is combined with surface runoff in the sewer depends on the sewer design, before the 20th century, sewers usually discharged into a body of water such as a stream, river, lake, bay, or ocean. There was no treatment, so the breakdown of the waste was left to the ecosystem. Today, the goal is that sewers route their contents to a treatment plant rather than directly to a body of water. In many countries, this is the norm, in developing countries. Thus other goals of modern sewage routing include handling surface runoff separately from sewage, handling greywater separately from toilet waste, proper collection and safe, nuisance-free disposal of the liquid wastes of a community are legally recognized as a necessity in an urbanized, industrialized society. In many developing countries the bulk of domestic and industrial wastewater is discharged without any treatment or after primary treatment only, the term sewage is nowadays regarded as an older term and is being more and more replaced by wastewater. In general American English usage, the sewage and sewerage mean the same thing. Both words are descended from Old French assewer, derived from the Latin exaquare, in American technical and professional English usage, sewerage refers to the infrastructure that conveys sewage. Wastes that result from an industrial processes such as the production or manufacture of goods are classed as industrial wastewater, surface runoff, also known as storm flow or overland flow, is that portion of precipitation that runs rapidly over the ground surface to a defined channel. Sewage is a mixture of chemicals, with many distinctive chemical characteristics. These include high concentrations of ammonium, nitrate, phosphorus, high conductivity, high alkalinity, the organic matter of sewage is measured by determining its biological oxygen demand or the chemical oxygen demand. Sewage also contains the nutrients nitrogen and phosphorus, Sewage can be monitored for both disease-causing and benign organisms with a variety of techniques. Traditional techniques involve filtering, staining, and examining samples under a microscope, sequencing DNA from an environmental sample is known as metagenomics. Sewage has also analyzed to determine relative rates of use of prescription

Heap leaching
–
The solution then percolates through the heap and leaches both the target and other minerals. This process, called the cycle, generally takes from one or two months for simple oxide ores to two years. Ultimate recovery of the mineral can range from 30% of contained to over 90% for the easiest to leach ores. In recent years, the addition of a drum has improved on the heap leaching process by allowing for a more efficient leach. The rotary drum agglomerator, such as the tyre driven Sepro Agglomeration Drum works by taking the crushed ore fines and this makes it much easier for the leaching solution to percolate through the pile, making its way through the channels between particles. The dismissal of these mechanisms can result in a number of practical and financial problems that will resonate throughout the life of the heap impacting the financial return of the operation, the crushed ore is irrigated with a dilute alkaline cyanide solution. The solution containing the precious metals continues percolating through the crushed ore until it reaches the liner at the bottom of the heap where it drains into a storage pond. The production of one gold ring through this method, can generate 20 tons of waste material, the fine product can be either doré or zinc-gold sludge that is then refined elsewhere. The method is similar to the method, above, except sulfuric acid is used to dissolve copper from its ores. The acid is recycled from the solvent extraction circuit and reused on the leach pad, a byproduct is iron sulfate, jarosite, which is produced as a byproduct of leaching pyrite, and sometimes even the same sulfuric acid that is needed for the process. Both oxide and sulfide ores can be leached, though the leach cycles are much different, in 2011 leaching produced 3.4 million metric tons of copper,22 percent of world production. The largest copper heap leach operations are in Chile, Peru, although the heap leaching is a low cost-process, it normally has recovery rates of 60-70%, although there are exceptions. It is normally most profitable with low-grade ores, higher-grade ores are usually put through more complex milling processes where higher recoveries justify the extra cost. The process chosen depends on the properties of the ore, the final product is cathode copper. The method is a heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. There currently are no operating commercial scale nickel laterite heap leach operations, thus, a unique feature of nickel heap leaching is the need for a tailings disposal area. The final product can be nickel hydroxide precipitates or mixed metal hydroxide precipitates, similar to copper oxide heap leaching, also using dilute sulfuric acid. Rio Tinto is commercializing this technology in Namibia and Australia, the French nuclear power company Areva in Niger and Namibia, the final product is yellowcake and requires significant further processing to produce fuel-grade feed

Drainage
–
Drainage is the natural or artificial removal of surface and sub-surface water from an area. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging, all houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered drains, which lined the major streets, the invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. New drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into, geotextiles are synthetic textile fabrics specially manufactured for civil and environmental engineering applications. Geotextiles are designed to retain fine soil particles while allowing water to pass through, in a typical drainage system they would be laid along a trench which would then be filled with coarse granular material, gravel, sea shells, stone or rock. The geotextile is then folded over the top of the stone, groundwater seeps through the geotextile and flow within the stone to an outfell. In high groundwater conditions a perforated pipe is laid along the base of the drain to increases the volume of water transported in the drain. Alternatively, the prefabricated plastic drainage system made of HDPE called SmartDitch, often incorporating geotextile, over the past 30 years geotextile and PVC filters have become the most commonly used soil filter media. They are cheap to produce and easy to lay, with factory controlled properties that ensure long term filtration performance even in fine silty soil conditions, seattles Public Utilities created a pilot program called Street Edge Alternatives Project. The project focuses on designing a system to provide drainage that more closely mimics the natural landscape prior to development than traditional piped systems, the streets are characterized by ditches along the side of the roadway, with plantings designed throughout the area. An emphasis on non curbed sidewalks allows water to more freely into the areas of permeable surface on the side of the streets. Because of the plantings the run off water from the area does not all directly go into the ground. Sustainable Urban Drainage Systems are designed to encourage contractors to install drainage system that closely mimic the natural flow of water in nature. Since 2010 local and neighbourhood planning in the UK is required by law to factor SUDS into any development projects that they are responsible for, slot drainage has proved the most breakthrough product of the last twenty years as a drainage option. Both stainless steel and concrete channel slot drainage have become industry standards on construction projects, the civil engineer is responsible for drainage in construction projects. They set out from the all the roads, street gutters, drainage, culverts. During the construction process he/she will set out all the levels for each of the previously mentioned factors. Civil engineers and construction managers work alongside architects and supervisors, planners, quantity surveyors, typically, most jurisdictions have some body of drainage law to govern to what degree a landowner can alter the drainage from his parcel

Osmaniye
–
Osmaniye is a city in the Çukurova region of Turkey, the capital of Osmaniye Province. Osmaniye is at an elevation of 125 meters, the Islamic presence in the area was first established by the Abbasid Caliph Harun Rashid, auxiliaries in his army being the first Turks to fight in Anatolia. They obviously took a shine to the place and following the Turkish victory over the Byzantines at Malazgirt in 1071 waves of Turkish conquest began, the Nur Mountains were settled by the Ulaşlı tribe of the Turkmens. The Ulaşlı remained the power through into the period of the Ottoman Empire and were even involved in the Celali uprisings. Eventually, in 1865 the Ottoman general Derviş Paşa was charged with bringing law and he established his headquarters in the Osmaniye villages of Dereobası, Fakıuşağı, Akyar and brought the Ulaşlı down from the high mountains to the village of Hacıosmanlı. This eventually became the province of Osmaniye, the city of Osmaniye was formally a district governorate and between 1924 and 1933 capital of the province. However, in 1933 the province was abolished and Osmaniye was made the district governorate of Adana province which continued till 1996, today Osmaniye is a conservative country town, the centre of a rich agricultural region well watered by the Ceyhan river system and well known for growing peanuts. There is plenty of forest too and much of the countryside is very attractive. However, the town was made a capital in 1996 and as such is now receiving some investment in infrastructure. There is a road, and taller buildings. The cuisine is typical of the region, kabab, şalgam, the local specialty is a kind of bread/pretzel called simit and tirşik, toğga. etc. In summer the weather is hot, and most residents of Osmaniye try to escape either to the nearby Mediterranean coast or up into the Nur mountains. The plateau of Zorkun is a mountain retreat in summertime. There are also 2 Roman cities remaining, consisting of roads and antique theater, called Hieropolis, the city is only 25 km from the Mediterranean coast of Dörtyol. Summers are very hot and dry while the winters are cool, antique ruins of Osmaniye, Karatepe and Aslantaş.

Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Blueberry
–
Blueberries are perennial flowering plants with indigo-colored berries from the section Cyanococcus within the genus Vaccinium. Species in the section Cyanococcus are the most common fruits sold as blueberries and are native to North America, Blueberries are usually erect, prostrate shrubs that can vary in size from 10 centimeters to 4 meters in height. In the commercial production of blueberries, the species are known as lowbush blueberries. The leaves can be deciduous or evergreen, ovate to lanceolate. The flowers are bell-shaped, white, pale pink or red, the fruit is a berry 5–16 millimeters in diameter with a flared crown at the end, they are pale greenish at first, then reddish-purple, and finally dark purple when ripe. They are covered in a coating of powdery epicuticular wax. They have a sweet taste when mature, with variable acidity, the genus Vaccinium has a mostly circumpolar distribution, with species mainly being present in North America, Europe, Asia and Africa. Many commercially sold species with English common names including blueberry are currently classified in section Cyanococcus of the genus Vaccinium, many North American native species of blueberries are grown commercially in the Southern Hemisphere in Australia, New Zealand and South American nations. See the Identification section for more information, note, habitat and range summaries are from the Flora of New Brunswick, published in 1986 by Harold R. These species are sometimes called blueberries and sold as jam or other products. The names of blueberries in languages other than English often translate as blueberry, e. g. Scots blaeberry, blaeberry, blåbær and French myrtilles usually refer to the European native bilberry, while bleuets refers to the North American blueberry. Russian голубика does not refer to blueberries, which are non-native and nearly unknown in Russia, Cyanococcus blueberries can be distinguished from the nearly identical-looking bilberries by their flesh color when cut in half. Ripe blueberries have light green flesh, while bilberries, whortleberries and huckleberries are red or purple throughout, Blueberries may be cultivated, or they may be picked from semiwild or wild bushes. In North America, the most common cultivated species is V. corymbosum, hybrids of this with other Vaccinium species adapted to southern U. S. climates are known collectively as southern highbush blueberries. So-called wild blueberries, smaller than cultivated highbush ones, have intense color, the lowbush blueberry, V. angustifolium, is found from the Atlantic provinces westward to Quebec and southward to Michigan and West Virginia. In some areas, it produces natural blueberry barrens, where it is the dominant species covering large areas, several First Nations communities in Ontario are involved in harvesting wild blueberries. Wild has been adopted as a term for harvests of managed native stands of lowbush blueberries. The bushes are not planted or genetically manipulated, but they are pruned or burned over two years, and pests are managed

Southwestern United States
–
The population of the area is around 11 million people, with over half that in Arizona, the most populous cities are Phoenix, El Paso, Las Vegas, Albuquerque, and Tucson. Most of the area was part of the Viceroyalty of New Spain in the Spanish Empire before becoming part of Mexico and it became part of the United States through the Treaty of Guadalupe Hidalgo and the Gadsden Purchase. The deserts dominate the southern and western reaches of the area, the two major rivers of the region are the Colorado River, running in the northern and western areas, and the Rio Grande, running in the south. Formed approximately 8000 years ago, the Chihuahuan Desert is a dry desert. The Chihuahuan Desert spreads across the portion of the region, covering from southeastern Arizona, across southern New Mexico. While it is the second largest desert in the United States, only a third of the desert is within the United States, El Paso is the major city in this desert, with other smaller cities being Las Cruces and Roswell in New Mexico. The Chihuahuan is a rain shadow desert, formed two mountain ranges which block oceanic precipitation from reaching the area. The most prolific plants in this region are agave, yucca and creosote bushes, when people think of the desert southwest, the landscape of the Sonoran Desert is what mostly comes to mind. Rainfall averages between 4–12 inches per year, and the deserts most widely known inhabitant is the saguaro cactus and it is bounded on the northwest by the Mojave Desert, to the north by the Colorado Plateau and to the east by the Arizona Mountains forests and the Chihuahuan Desert. The portion of the Sonora Desert which lies in the Southwestern United States is the most populated area within the region. Six of the top ten major population centers of the region are found within its borders, Phoenix, Tucson, Mesa, Chandler, Glendale, also within its borders are Yuma and Prescott Arizona. The most northwest portion of the American Southwest is covered by the Mojave Desert, bordered on the south by the Sonoran Desert and the east by the Colorado Plateau, its range within the region makes up the southeast tip of Nevada, and the northwestern corner of Arizona. In terms of topography, the Mojave is very similar to the Great Basin Desert, the Mojave is the smallest, driest and hottest desert within the United States. The Mojave gets less than six inches of rain annually, the most prolific vegetation is the tall Joshua tree, which grow as tall as 40 feet, and are thought to live almost 1000 years. Other major vegetation includes the Parry saltbush and the Mojave sage, the Colorado Plateau varies from the large stands of forests in the west, including the largest stand of ponderosa pine trees in the world, to the Mesas to the east. Although not called a desert, the Colorado Plateau is mostly made up of high desert, the Plateau is characterized by a series of plateaus and mesas, interspersed with canyons. The most dramatic example is the Grand Canyon, but that is one of many dramatic vistas included within the Plateau, which includes spectacular lava formations, painted deserts, sand dunes, and badlands. One of the most distinctive features of the Plateau is its longevity, the Plateau can be divided into six sections, three of which fall into the Southwest region

Rain
–
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated—that is, become heavy enough to fall under gravity. Rain is a component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for power plants. The major cause of production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds such as cumulonimbus which can organize into narrow rainbands. On the leeward side of mountains, desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass, the movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes. The urban heat island effect leads to increased rainfall, both in amounts and intensity, downwind of cities, global warming is also causing changes in the precipitation pattern globally, including wetter conditions across eastern North America and drier conditions in the tropics. The globally averaged annual precipitation over land is 715 mm, climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Rainfall is measured using rain gauges, rainfall amounts can be estimated by weather radar. Rain is also known or suspected on other planets, where it may be composed of methane, neon, sulfuric acid, or even iron rather than water. Air contains water vapor, and the amount of water in a mass of dry air. The amount of moisture in air is commonly reported as relative humidity. How much water vapor a parcel of air can contain before it becomes saturated, warmer air can contain more water vapor than cooler air before becoming saturated. Therefore, one way to saturate a parcel of air is to cool it, the dew point is the temperature to which a parcel must be cooled in order to become saturated. There are four mechanisms for cooling the air to its dew point, adiabatic cooling, conductive cooling, radiational cooling. Adiabatic cooling occurs when air rises and expands, the air can rise due to convection, large-scale atmospheric motions, or a physical barrier such as a mountain. Conductive cooling occurs when the air comes into contact with a surface, usually by being blown from one surface to another. Radiational cooling occurs due to the emission of infrared radiation, either by the air or by the surface underneath, evaporative cooling occurs when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature, or until it reaches saturation

Reservoir
–
A reservoir is a storage space for fluids. These fluids may be water, hydrocarbons or gas, a reservoir usually means an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water. Reservoirs can be created by controlling a stream that drains a body of water. They can also be constructed in river valleys using a dam, alternately, a reservoir can be built by excavating flat ground or constructing retaining walls and levees. Tank reservoirs store liquids or gases in storage tanks that may be elevated, at grade level, tank reservoirs for water are also called cisterns. Underground reservoirs are used to store liquids, principally either water or petroleum, a dam constructed in a valley relies on the natural topography to provide most of the basin of the reservoir. Dams are typically located at a part of a valley downstream of a natural basin. The valley sides act as walls, with the dam located at the narrowest practical point to provide strength. In many reservoir construction projects, people have to be moved and re-housed, construction of a reservoir in a valley will usually need the river to be diverted during part of the build, often through a temporary tunnel or by-pass channel. In hilly regions, reservoirs are constructed by enlarging existing lakes. Sometimes in such reservoirs the new top water level exceeds the height on one or more of the feeder streams such as at Llyn Clywedog in Mid Wales. In such cases additional side dams are required to contain the reservoir, where water is pumped or siphoned from a river of variable quality or quantity, bank-side reservoirs may be built to store the water. Such reservoirs are usually formed partly by excavation and partly by building a complete encircling bund or embankment, the water stored in such reservoirs may stay there for several months, during which time normal biological processes may substantially reduce many contaminants and almost eliminate any turbidity. The use of reservoirs also allows water abstraction to be stopped for some time. Service reservoirs store fully treated potable water close to the point of distribution, many service reservoirs are constructed as water towers, often as elevated structures on concrete pillars where the landscape is relatively flat. Other service reservoirs can be almost entirely underground, especially in hilly or mountainous country. In the United Kingdom, Thames Water has many underground reservoirs, sometimes called cisterns, built in the 1800s. A good example is the Honor Oak Reservoir in London, constructed between 1901 and 1909, when it was completed it was said to be the largest brick built underground reservoir in the world and it is still one of the largest in Europe

Girnar
–
Girnar, also known as Girinagar or Revatak Pravata, is a group of mountains in the Junagadh District of Gujarat, India, situated near Junagadh. Older than the Himalayas, Girnar, the mountain and its range are considered sacred and it is an important pilgrimage site for both Jains and Hindus, who gather here during the Girnar Parikrama festival. Girnar hosts a number of temples and some historical spots across its range, amidst the lush green Gir Forest, the mountain range serves as the hub of religious activity. For Jains this place is considered holy as Nirvana Kshetra and Nirvan bhumi of 22nd Tirthankara Neminath & For Hindus this place is considered holy as Dattatreya stayed there, also, this place is associated with the death of the mighty Yavana warrior Kalayavana in Dwaparyug. Contemplating an absolutely undisturbed sleep he was given a boon that anyone who dared to disturb his sleep would get burnt to ashes immediately. Fast forward to Dwaparyug, in the deep inside the cave, Kalayavan mistakenly wakes up Muchukunda from his sleep. Then Muchukunda was delighted to see Lord Shri Krisha there, who was none other than Lord Vishnu and this story is very popular in Srimad Bhagavata. Lord Damodar here is considered as Adhipati of Girnar Kshetra. This place is holy for Vaishnavaits. Notwithstanding the story though, today Mount Girnar is even more popular as a Shaiva and this mountain was considered holy to Buddhists as well. According to tradition, Pavhari Baba, who had an influence on Swami Vivekananda was first initiated into the mysteries of practical yoga on the top of mount Girnar. The mountain Girnar is older than the Himalayas and the Jain temples upon it are amongst the most ancient in the country and it is 3666 feet high, and is one of the most remarkable mountains in India. Girnar was anciently called Raivata or Urjjayanta, sacred amongst the Jains to Neminath, the 22nd Tirthankar, the base of the mountain, known as Girnar Taleti, is about 4 km east of the center of Junagadh. There are temples and other sacred places all along this stretch, the traveller, in order to reach Girnar Taleti from Junagadh city, will pass through the Wagheshwari or Vagheshwari Gate, which is close to the Uparkot fort area, Easterly. At about 200 metres from the gate, to the right of the road, is the Temple of Wagheshwari, an ancient Verai Mata mandir and a modern Gayatri Shakti Peeth mandir are nearby. About a furlong beyond this is a bridge, and just beyond it on the right are the Ashokas Major Rock Edicts. The edicts are inscribed high up on a large, domed mass of black granite measuring roughly 20 feet x 30 feet, the inscription is in Brahmi script. This is dedicated to Damodar, a name of Krishna, from Dam, the reservoir, Damodar Kund, at this place is accounted very sacred. Next is an old shrine of Bhavnath, a form of Shiva, close to Girnar Taleti, Mrigi kund, most persons who are not active climbers will probably proceed up the mountain in a swing doli from Taleti

Canal
–
Canals and navigations are human-made channels for water conveyance, or to service water transport vehicles. In the vernacular, both are referred to as canals, and in most cases, the works will have a series of dams. These areas are referred to as water levels, often just called levels. In contrast, a canal cuts across a drainage divide atop a ridge, many canals have been built at elevations towering over valleys and others water ways crossing far below. Cities need a lot of water and many canals with sources of water at a higher level can deliver water to a destination where there is a lack of water. The Roman Empires Aqueducts were such water supply canals, a navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river, a vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal is a channel that cuts across a drainage divide, most commercially important canals of the first half of the 19th century were a little of each, using rivers in long stretches, and divide crossing canals in others. This is true for many canals still in use, there are two broad types of canal, Waterways, canals and navigations used for carrying vessels transporting goods and people. These can be subdivided into two kinds, Those connecting existing lakes, rivers, other canals or seas and oceans and those connected in a city network, such as the Canal Grande and others of Venice Italy, the gracht of Amsterdam, and the waterways of Bangkok. Aqueducts, water canals that are used for the conveyance and delivery of potable water for human consumption, municipal uses, hydro power canals. Historically canals were of importance to commerce and the development, growth. In 1855 the Lehigh Canal carried over 1.2 million tons of burning anthracite coal, by the 1930s the company which built. By the early 1880s, canals which had little ability to compete with rail transport, were off the map. In the next couple of decades, coal was diminished as the heating fuel of choice by oil. Later, after World War I when motor-trucks came into their own, Canals are built in one of three ways, or a combination of the three, depending on available water and available path, Human made streams A canal can be created where no stream presently exists. Either the body of the canal is dug or the sides of the canal are created by making dykes or levees by piling dirt, stone, the water for the canal must be provided from an external source, like streams or reservoirs. Where the new waterway must change elevation engineering works like locks, lifts or elevators are constructed to raise, examples include canals that connect valleys over a higher body of land, like Canal du Midi, Canal de Briare and the Panama Canal

Mesopotamia
–
In the Iron Age, it was controlled by the Neo-Assyrian and Neo-Babylonian Empires. The Sumerians and Akkadians dominated Mesopotamia from the beginning of history to the fall of Babylon in 539 BC. It fell to Alexander the Great in 332 BC, and after his death, around 150 BC, Mesopotamia was under the control of the Parthian Empire. Mesopotamia became a battleground between the Romans and Parthians, with parts of Mesopotamia coming under ephemeral Roman control. In AD226, eastern part of it fell to the Sassanid Persians, division of Mesopotamia between Roman and Sassanid Empires lasted until the 7th century Muslim conquest of Persia of the Sasanian Empire and Muslim conquest of the Levant from Byzantines. A number of primarily neo-Assyrian and Christian native Mesopotamian states existed between the 1st century BC and 3rd century AD, including Adiabene, Osroene, and Hatra, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. The regional toponym Mesopotamia comes from the ancient Greek root words μέσος middle and ποταμός river and it is used throughout the Greek Septuagint to translate the Hebrew equivalent Naharaim. In the Anabasis, Mesopotamia was used to designate the land east of the Euphrates in north Syria, the Aramaic term biritum/birit narim corresponded to a similar geographical concept. The neighbouring steppes to the west of the Euphrates and the part of the Zagros Mountains are also often included under the wider term Mesopotamia. A further distinction is made between Northern or Upper Mesopotamia and Southern or Lower Mesopotamia. Upper Mesopotamia, also known as the Jazira, is the area between the Euphrates and the Tigris from their sources down to Baghdad, Lower Mesopotamia is the area from Baghdad to the Persian Gulf and includes Kuwait and parts of western Iran. In modern academic usage, the term Mesopotamia often also has a chronological connotation and it is usually used to designate the area until the Muslim conquests, with names like Syria, Jazirah, and Iraq being used to describe the region after that date. It has been argued that these later euphemisms are Eurocentric terms attributed to the region in the midst of various 19th-century Western encroachments, Mesopotamia encompasses the land between the Euphrates and Tigris rivers, both of which have their headwaters in the Armenian Highlands. Both rivers are fed by tributaries, and the entire river system drains a vast mountainous region. Overland routes in Mesopotamia usually follow the Euphrates because the banks of the Tigris are frequently steep and difficult. The climate of the region is semi-arid with a vast desert expanse in the north which gives way to a 15,000 square kilometres region of marshes, lagoons, mud flats, in the extreme south, the Euphrates and the Tigris unite and empty into the Persian Gulf. In the marshlands to the south of the area, a complex water-borne fishing culture has existed since prehistoric times, periodic breakdowns in the cultural system have occurred for a number of reasons. Alternatively, military vulnerability to invasion from marginal hill tribes or nomadic pastoralists has led to periods of trade collapse and these trends have continued to the present day in Iraq

Flooding of the Nile
–
The flooding of the Nile has been an important natural cycle in Egypt since ancient times. It is celebrated by Egyptians as a holiday for two weeks starting August 15, known as Wafaa El-Nil. It is also celebrated in the Coptic Church by ceremonially throwing a martyrs relic into the river, hence the name, ancient Egyptians believed that the Nile flooded every year because of Isiss tears of sorrow for her dead husband, Osiris. The flooding of the Nile is the result of the monsoon between May and August causing enormous precipitations on the Ethiopian Highlands whose summits reach heights of up to 4550 m. Most of this rainwater is taken by the Blue Nile and by the Atbara into the Nile, an important amount is flowing through the Sobat. During this short period, those rivers contribute up to ninety percent of the water of the Nile and most of the sedimentation carried by it and these facts were unknown to the ancient Egyptians who could only observe the rise and fall of the Nile waters. Which was not foreseeable, of course, was the size of flooding, the Egyptian year was divided into the three seasons of Akhet, Peret, and Shemu. Akhet covered the Egyptian flood cycle and this cycle was so consistent that the Egyptians timed its onset using the heliacal rising of Sirius, the key event used to set their calendar. The Nile continued to rise until the beginning of September, when the level remained stationary for a period of three weeks, sometimes a little less. In October it often rose again, and reached its highest level, from this period it began to subside, and usually sank steadily until the month of June when it reached its lowest level, again. Flooding reached Aswan about an earlier than Cairo, and Luxor 5 –6 days earlier than Cairo. Typical heights of flood were 45 feet at Aswan,38 feet at Luxor and 25 feet at Cairo, if it were not for the Nile River, Egyptian civilization could not have developed, as it is the only significant source of water in this desert region. Its other importance was its function as their gateway to the unknown world, the Nile flows from south to north, to its delta on the Mediterranean Sea. The floods were seen as the coming of the god. Possibly Egyptian mythology was based on understanding, creating stories of gods or nature to give added importance to the processes and cycles that sustained Egypt. Whilst the earliest Egyptians simply laboured those areas which were inundated by the floods, some 7000 years ago, agricultural land was divided into large fields surrounded by dams and dykes and equipped with intake and exit canals. The basins were flooded and then closed for about 45 days to saturate the soil with moisture, then the water was discharged to lower fields or back into the Nile. Immediately thereafter, sowing started, and harvesting followed some three of four months later, in the dry season thereafter, farming was not possible

Watercourse
–
A watercourse is the channel that a flowing body of water follows. In the UK, some aspects of law such as The Rivers Act 1951 specify that a watercourse includes those rivers which are dry for part of the year. In some jurisdictions owners of land over which the flows may have rights to some or much of the water in a legal sense. These include estuaries, rivers, streams, anabranches and canals, if it is navigable it is also a waterway. A navigable waterway may be defined under law in the United States differently from other countries.

Pharaoh
–
The word pharaoh ultimately derive from the Egyptian compound pr-ˤ3 great house, written with the two biliteral hieroglyphs pr house and ˤ3 column, here meaning great or high. It was used only in larger phrases such as smr pr-ˤ3 Courtier of the High House, with specific reference to the buildings of the court or palace. From the twelfth dynasty onward, the word appears in a wish formula Great House, may it live, prosper, and be in health, but again only with reference to the royal palace and not the person. During the reign of Thutmose III in the New Kingdom, after the rule of the Hyksos during the Second Intermediate Period. During the eighteenth dynasty the title pharaoh was employed as a designation of the ruler. From the nineteenth dynasty onward pr-ˤ3 on its own was used as regularly as hm. f, the term, therefore, evolved from a word specifically referring to a building to a respectful designation for the ruler, particularly by the twenty-second dynasty and twenty-third dynasty. For instance, the first dated appearance of the pharaoh being attached to a rulers name occurs in Year 17 of Siamun on a fragment from the Karnak Priestly Annals. Here, an induction of an individual to the Amun priesthood is dated specifically to the reign of Pharaoh Siamun and this new practice was continued under his successor Psusennes II and the twenty-second dynasty kings. Shoshenq I was the successor of Siamun. Meanwhile, the old custom of referring to the sovereign simply as pr-ˤ3 continued in traditional Egyptian narratives, by this time, the Late Egyptian word is reconstructed to have been pronounced *par-ʕoʔ whence Herodotus derived the name of one of the Egyptian kings, Φερων. In the Bible, the title also occurs as פרעה, from that, Septuagint φαραώ pharaō and then Late Latin pharaō, both -n stem nouns. The Quran likewise spells it فرعون firawn with n, interestingly, the Arabic combines the original pharyngeal ayin sound from Egyptian, along with the -n ending from Greek. English at first spelt it Pharao, but the King James Bible revived Pharaoh with h from the Hebrew, meanwhile in Egypt itself, *par-ʕoʔ evolved into Sahidic Coptic ⲡⲣ̅ⲣⲟ prro and then rro. Scepters and staves were a sign of authority in ancient Egypt. One of the earliest royal scepters was discovered in the tomb of Khasekhemwy in Abydos, kings were also known to carry a staff, and Pharaoh Anedjib is shown on stone vessels carrying a so-called mks-staff. The scepter with the longest history seems to be the heqa-scepter, the earliest examples of this piece of regalia dates to pre-dynastic times. A scepter was found in a tomb at Abydos that dates to the late Naqada period, another scepter associated with the king is the was-scepter. This is a long staff mounted with an animal head, the earliest known depictions of the was-scepter date to the first dynasty

Amenemhat III
–
See Amenemhat, for other individuals with this name. Amenemhat III, also spelled Amenemhet III, was a pharaoh of the Twelfth Dynasty of Egypt. He ruled from c.1860 BC to c.1814 BC and his reign is regarded as the golden age of the Middle Kingdom. He may have had a coregency with his father, Senusret III. His daughter, Sobekneferu, later succeeded Amenemhat IV, as the last ruler of the twelfth dynasty, Amenemhat IIIs throne name, Nimaatre, means Belonging to the Justice of Re. He built his first pyramid at Dahshur, but there were construction problems, around Year 15 of his reign the king decided to build a new pyramid at Hawara, near the Faiyum. The pyramid at Dahshur was used as ground for several royal women. The mortuary temple attached to the Hawara pyramid may have known to Herodotus and Diodorus Siculus as the Labyrinth. Strabo praised it as a wonder of the world, nevertheless, the kings burial was robbed in antiquity. His daughter or sister, Neferuptah, was buried in a separate pyramid 2 km southwest of the kings, the pyramidion of Amenemhet IIIs pyramid tomb was found toppled from the peak of its structure and preserved relatively intact, it is today located in the Cairo Egyptian Museum. There is very little evidence for military expeditions in the reign of the king, there is only one record for a small mission in year nine of the king. The evidence for that was found in an inscription in Nubia. The short text reports that a mission was guided by the mouth of Nekhen Zamonth who reports that he went north with a small troop. Many expeditions to mining areas are recorded under the king, there are two expeditions known to the Wadi el-Hudi at the southern border of Egypt, where Amethyst was collected. One of the dates to year 11, of the king. Two further to year 20 and to year 28, there were further mining expeditions to the Wadi Hammamat. These are dated to year 2,3,19,20 and 33 of the kings reign, the inscriptions of year 19 and 20 might be related to the building start of the pyramid complex at Hawara. They report the breaking of stone for statues, at the Red Sea coast, at Mersa was discovered a stela mentioning an expedition to Punt under Amenemhat III

Common Era
–
Common Era or Current Era is a year-numbering system for the Julian and Gregorian calendars that refers to the years since the start of this era, i. e. since AD1. The preceding era is referred to as before the Common or Current Era, the Current Era notation system can be used as a secular alternative to the Dionysian era system, which distinguishes eras as AD and BC. The two notation systems are equivalent, thus 2017 CE corresponds to AD2017 and 400 BCE corresponds to 400 BC. The year-numbering system for the Gregorian calendar is the most widespread civil calendar used in the world today. For decades, it has been the standard, recognized by international institutions such as the United Nations. The expression has been traced back to Latin usage to 1615, as vulgaris aerae, the term Common Era can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish academics. He attempted to number years from a reference date, an event he referred to as the Incarnation of Jesus. Dionysius labeled the column of the table in which he introduced the new era as Anni Domini Nostri Jesu Christi, numbering years in this manner became more widespread in Europe with its usage by Bede in England in 731. Bede also introduced the practice of dating years before what he supposed was the year of birth of Jesus, in 1422, Portugal became the last Western European country to switch to the system begun by Dionysius. The first use of the Latin term vulgaris aerae discovered so far was in a 1615 book by Johannes Kepler, Kepler uses it again in a 1616 table of ephemerides, and again in 1617. A1635 English edition of that book has the title page in English – so far, a 1701 book edited by John LeClerc includes Before Christ according to the Vulgar Æra,6. A1716 book in English by Dean Humphrey Prideaux says, before the beginning of the vulgar æra, a 1796 book uses the term vulgar era of the nativity. The first so-far-discovered usage of Christian Era is as the Latin phrase aerae christianae on the page of a 1584 theology book. In 1649, the Latin phrase æræ Christianæ appeared in the title of an English almanac, a 1652 ephemeris is the first instance so-far-found for English usage of Christian Era. The English phrase common Era appears at least as early as 1708, a 1759 history book uses common æra in a generic sense, to refer to the common era of the Jews. The first-so-far found usage of the phrase before the era is in a 1770 work that also uses common era and vulgar era as synonyms. The 1797 edition of the Encyclopædia Britannica uses the terms vulgar era, the Catholic Encyclopedia in at least one article reports all three terms being commonly understood by the early 20th century. Thus, the era of the Jews, the common era of the Mahometans, common era of the world

Faiyum Oasis
–
The Faiyum Oasis is a depression or basin in the desert immediately to the west of the Nile south of Cairo. The extent of the area is estimated at between 1,270 km² and 1700 km². The basin floor comprises fields watered by a channel of the Nile, the lake was freshwater in prehistory but is today a saltwater lake. It is a source for tilapia and other fish for the local area, differing from typical oases, whose fertility depends on water obtained from springs, the cultivated land in the Faiyum is formed of Nile mud brought down by the Bahr Yussef,24 km in length. Between the beginning of Bahr Yussef at El Lahun to its end at the city of Faiyum, the drainage water flows into Lake Moeris. When the Mediterranean Sea was a hot dry hollow near the end of the Messinian Salinity Crisis in the late Miocene, Faiyum was a dry hollow, and the Nile flowed past it at the bottom of a canyon. After the Mediterranean reflooded at the end of the Miocene, the Nile canyon became an arm of the sea reaching inland further than Aswan, over geological time that sea arm gradually filled with silt and became the Nile valley. Eventually the Nile valley bed silted up high enough to let the Nile in flood overflow into the Faiyum hollow, the lake is first recorded from about 3000 BC, around the time of Menes. However, for the most part it would only be filled with flood waters. The lake was bordered by settlements, and the town of Crocodilopolis grew up on the south where the higher ground created a ridge. In 2300 BC, the waterway from the Nile to the lake was widened and deepened to make a canal which is now known as the Bahr Yussef. This canal fed into the lake and this was meant to serve three purposes, control the flooding of the Nile, regulate the water level of the Nile during dry seasons, and serve the surrounding area with irrigation. There is evidence of ancient Egyptian pharaohs of the twelfth dynasty using the lake of Faiyum as a reservoir to store surpluses of water for use during the dry periods. The lake was abandoned due to the nearest branch of the Nile dwindling in size from 230 BC. Faiyum was known to the ancient Egyptians as the twenty-first nome of Upper Egypt, in ancient Egyptian times, its capital was Sh-d-y-t, called by the Greeks Crocodilopolis, and refounded by Ptolemy II as Arsinoe. Faiyum became one of the breadbaskets of the Roman world, the Egyptians continued their practice of burying their dead, despite the Roman preference for cremation. Preserved by the dry environment, these Faiyum portraits make up the richest body of portraiture to have survived from antiquity. They provide us with a window into a society of peoples of mixed origins —Egyptians, Greeks, Romans, Syrians, Libyans

Nile
–
The Nile is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, in particular, the Nile is the primary water source of Egypt and Sudan. The Nile has two tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself, the Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa and it flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast, the two rivers meet just north of the Sudanese capital of Khartoum. The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta, Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, in the ancient Egyptian language, the Nile is called Ḥpī or Iteru, meaning river. In Coptic, the words piaro or phiaro meaning the river come from the ancient name. The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος, beyond that, however, the etymology is disputed. One possible etymology derives it from a Semitic Nahal, meaning river, the standard English names White Nile and Blue Nile, to refer to the rivers source, derive from Arabic names formerly applied only to the Sudanese stretches which meet at Khartoum. Above Khartoum, the Nile is also known as the White Nile, at Khartoum the river is joined by the Blue Nile. The White Nile starts in equatorial East Africa, and the Blue Nile begins in Ethiopia, both branches are on the western flanks of the East African Rift. The drainage basin of the Nile covers 3,254,555 square kilometers, the source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. It is either the Ruvyironza, which emerges in Bururi Province, Burundi, or the Nyabarongo, the two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border. Gish Abay is reportedly the place where the water of the first drops of the Blue Nile develop. The Nile leaves Lake Nyanza at Ripon Falls near Jinja, Uganda and it flows north for some 130 kilometers, to Lake Kyoga. For the remaining part it flows westerly through the Murchison Falls until it reaches the very northern shores of Lake Albert where it forms a significant river delta

Engineer
–
Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin words ingeniare and ingenium, the work of engineers forms the link between scientific discoveries and their subsequent applications to human and business needs and quality of life. His/her work is predominantly intellectual and varied and not of a mental or physical character. It requires the exercise of original thought and judgement and the ability to supervise the technical, he/she is thus placed in a position to make contributions to the development of engineering science or its applications. In due time he/she will be able to give authoritative technical advice, much of an engineers time is spent on researching, locating, applying, and transferring information. Indeed, research suggests engineers spend 56% of their time engaged in various information behaviours, Engineers must weigh different design choices on their merits and choose the solution that best matches the requirements. Their crucial and unique task is to identify, understand, Engineers apply techniques of engineering analysis in testing, production, or maintenance. Analytical engineers may supervise production in factories and elsewhere, determine the causes of a process failure and they also estimate the time and cost required to complete projects. Supervisory engineers are responsible for major components or entire projects, Engineering analysis involves the application of scientific analytic principles and processes to reveal the properties and state of the system, device or mechanism under study. Most engineers specialize in one or more engineering disciplines, numerous specialties are recognized by professional societies, and each of the major branches of engineering has numerous subdivisions. Civil engineering, for example, includes structural and transportation engineering and materials engineering include ceramic, metallurgical, mechanical engineering cuts across just about every discipline since its core essence is applied physics. Engineers also may specialize in one industry, such as vehicles, or in one type of technology. Several recent studies have investigated how engineers spend their time, that is, research suggests that there are several key themes present in engineers’ work, technical work, social work, computer-based work, information behaviours. Amongst other more detailed findings, a recent work sampling study found that engineers spend 62. 92% of their time engaged in work,40. 37% in social work. The time engineers spend engaged in activities is also reflected in the competencies required in engineering roles. There are many branches of engineering, each of which specializes in specific technologies, typically engineers will have deep knowledge in one area and basic knowledge in related areas. When developing a product, engineers work in interdisciplinary teams. For example, when building robots an engineering team will typically have at least three types of engineers, a mechanical engineer would design the body and actuators

Mughal Empire
–
The dynasty, though ethnically Turco-Mongol, was Persianate in terms of culture. The Mughal empire extended over parts of the Indian subcontinent. The beginning of the empire is conventionally dated to the victory by its founder Babur over Ibrahim Lodi, the Mughal emperors were Central Asian Turco-Mongols belonging to the Timurid dynasty, who claimed direct descent from both Genghis Khan and Timur. During the reign of Humayun, the successor of Babur, the empire was briefly interrupted by the Sur Empire, the classic period of the Mughal Empire started in 1556 with the ascension of Akbar the Great to the throne. Under the rule of Akbar and his son Jahangir, the region enjoyed economic progress as well as harmony. Akbar was a warrior who also forged alliances with several Hindu Rajput kingdoms. Some Rajput kingdoms continued to pose a significant threat to the Mughal dominance of northwestern India, the reign of Shah Jahan, the fifth emperor, between 1628 and 1658 was the golden age of Mughal architecture. He erected several monuments, the best known of which is the Taj Mahal at Agra, as well as the Moti Masjid, Agra, the Red Fort, the Jama Masjid, Delhi. By the mid-18th century, the Marathas had routed Mughal armies, during the following century Mughal power had become severely limited, and the last emperor, Bahadur Shah II, had authority over only the city of Shahjahanabad. He issued a firman supporting the Indian Rebellion of 1857 and following the defeat was therefore tried by the British East India Company for treason, imprisoned and exiled to Rangoon. Contemporaries referred to the empire founded by Babur as the Timurid empire, which reflected the heritage of his dynasty, another name was Hindustan, which was documented in the Ain-i-Akbari, and which has been described as the closest to an official name for the empire. In the west, the term Mughal was used for the emperor, and by extension, the use of Mughal derived from the Arabic and Persian corruption of Mongol, and it emphasised the Mongol origins of the Timurid dynasty. The term gained currency during the 19th century, but remains disputed by Indologists, similar terms had been used to refer to the empire, including Mogul and Moghul. Nevertheless, Baburs ancestors were sharply distinguished from the classical Mongols insofar as they were oriented towards Persian rather than Turco-Mongol culture, ousted from his ancestral domains in Central Asia, Babur turned to India to satisfy his ambitions. He established himself in Kabul and then pushed steadily southward into India from Afghanistan through the Khyber Pass, Baburs forces occupied much of northern India after his victory at Panipat in 1526. The preoccupation with wars and military campaigns, however, did not allow the new emperor to consolidate the gains he had made in India, the instability of the empire became evident under his son, Humayun, who was driven out of India and into Persia by rebels. Humayuns exile in Persia established diplomatic ties between the Safavid and Mughal Courts, and led to increasing Persian cultural influence in the Mughal Empire, the restoration of Mughal rule began after Humayuns triumphant return from Persia in 1555, but he died from a fatal accident shortly afterwards. Humayuns son, Akbar, succeeded to the throne under a regent, Bairam Khan, through warfare and diplomacy, Akbar was able to extend the empire in all directions and controlled almost the entire Indian subcontinent north of the Godavari River

Mughal emperors
–
The Mughal emperors were a branch of the Timurid dynasty. From the early 16th century to the early 18th they built and ruled the Mughal Empire on the Indian subcontinent, mainly corresponding to the countries of Bangladesh, India. Their power rapidly dwindled during the 18th century and the last of the emperors was deposed in 1857, with the establishment of the British Raj. The dynasty was of Asian Turco-Mongol origin from a now part of modern-day Uzbekistan. Timur is generally known in the West as Tamerlane the Great and its population at the time has been estimated as between 110 and 150 million, over a territory of more than 3.2 million square kilometres. Ousted from his domains in Central Asia by Uzbek Khan. He established himself in Kabul and then pushed steadily southward into India from Afghanistan through the Khyber Pass, baburs forces occupied much of northern India after his victory at Panipat in 1526. The preoccupation with wars and military campaigns, however, did not allow the new emperor to consolidate the gains he had made in India, the instability of the empire became evident under his son, Humayun, who was driven out of India and into Persia by rebels. Humayuns exile in Persia established diplomatic ties between the Safavid and Mughal Courts, and led to increasing West Asian cultural influence in the Mughal court, the restoration of Mughal rule began after Humayun’s triumphant return from Persia in 1555, but he died from a fatal accident shortly afterwards. Humayuns son, Akbar, succeeded to the throne under a regent, Bairam Khan, through warfare and diplomacy, Akbar was able to extend the empire in all directions, and controlled almost the entire Indian subcontinent north of the Godavari river. He created a new class of nobility loyal to him from the aristocracy of Indias social groups, implemented a modern government. At the same time Akbar intensified trade with European trading companies and he left his successors an internally stable state, which was in the midst of its golden age, but before long signs of political weakness would emerge. Akbars son, Jahangir, ruled the empire at its peak, but he was addicted to opium, neglected the affairs of the state, and came under the influence of rival court cliques. During the reign of Jahangirs son, Shah Jahan, the culture, the maintenance of the court, at this time, began to cost more than the revenue. Shah Jahans eldest son, the liberal Dara Shikoh, became regent in 1658, however, a younger son, Aurangzeb, allied with the Islamic orthodoxy against his brother, who championed a syncretistic Hindu-Muslim religion and culture, and ascended to the throne. Aurangzeb defeated Dara in 1659 and had him executed, although Shah Jahan fully recovered from his illness, Aurangzeb declared him incompetent to rule and had him imprisoned. During Aurangzebs reign, the empire gained political strength once more, Aurangzeb expanded the empire to include almost the whole of South Asia, but at his death in 1707, many parts of the empire were in open revolt. Aurangzebs son, Shah Alam, repealed the religious policies of his father, however, after his death in 1712, the Mughal dynasty sank into chaos and violent feuds

Bahadur Shah Zafar
–
Mirza Abu Zafar Sirajuddin Muhammad Bahadur Shah Zafar was the last Mughal emperor. He was the son of and became the successor to his father, Akbar II. He used Zafar, a part of his name, for his nom de plume as an Urdu poet and he was a nominal Emperor, as the Mughal Empire existed in name only and his authority was limited only to the city of Delhi. Following his involvement in the Indian Rebellion of 1857, the British exiled him to Rangoon in British-controlled Burma, Zafars father, Akbar II had been imprisoned by the British and he was not his father’s preferred choice as his successor. One of Akbar Shahs queens, Mumtaz Begum, pressured him to declare her son as his successor, however, The East India Company exiled Jahangir after he attacked their resident, in the Red Fort. Bahadur Shah Zafar presided over a Mughal Empire that only ruled the city Delhi, the Marathas installed Shah Alam II in the throne in 1772, under the protection of the Maratha general Mahadaji Shinde and maintained suzerainty over Mughal affairs in Delhi. The East India Company became the dominant political and military power in mid-nineteenth century India, outside the region controlled by the Company, hundreds of kingdoms and principalities, fragmented their land. The emperor was respected by the Company and had him a pension. The emperor permitted the Company to collect taxes from Delhi and maintain a force in it. Zafar never had any interest in statecraft or had any imperial ambition, after the Indian Rebellion of 1857, the British exiled him from Delhi. Bahadur Shah Zafar was a noted Urdu poet, having written a number of Urdu ghazals, while some part of his opus was lost or destroyed during the Indian Rebellion of 1857, a large collection did survive, and was compiled into the Kulliyyat-i-Zafar. The court that he maintained was home to several prolific Urdu writers, including Mirza Ghalib, Dagh, Mumin, because of his neutral views on religions, some Indian kings and regiments accepted Zafar as the Emperor of India. On 12 May 1857, Zafar held his first formal audience in years after defeating. It was attended by several sepoys who treated him familiarly or disrespectfully, when the sepoys first arrived at Bahadur Shah Zafar’s court, he asked them why they had come to him because he had no means of maintaining them. Bahadur Shah Zafar’s conduct was indecisive, however, he yielded to the demands of the sepoys when he was told that they would not be able to win against the East India Company without him. On 16 May, sepoys and palace servants killed 52 Europeans who were prisoners of the palace, the executions took place under a peepul tree in front of the palace, despite Zafars protests. The aim of the executioners who were not the supporters of Zafar was to him in the killings. Once he had joined them, Bahadur Shah II took ownership for all the actions of the mutineers, though Zafar was dismayed by the looting and disorder, he gave his public support to the rebellion

Nubia
–
Nubia is a region along the Nile river located in what is today northern Sudan and southern Egypt. It was the seat of one of the earliest civilizations of ancient Africa, with a history that can be traced from at least 2000 B. C. onward, and was home to one of the African empires. Nubia was again united within Ottoman Egypt in the 19th century, the name Nubia is derived from that of the Noba people, nomads who settled the area in the 4th century following the collapse of the kingdom of Meroë. The Noba spoke a Nilo-Saharan language, ancestral to Old Nubian, Old Nubian was mostly used in religious texts dating from the 8th and 15th centuries AD. Before the 4th century, and throughout classical antiquity, Nubia was known as Kush, or, in Classical Greek usage, until at least 1970, the Birgid language was spoken north of Nyala in Darfur, but is now extinct. Nubia was divided into two regions, Upper and Lower Nubia, so called because of their location in the Nile river valley. Early settlements sprouted in both Upper and Lower Nubia, Egyptians referred to Nubia as Ta-Seti, or The Land of the Bow, since the Nubians were known to be expert archers. Modern scholars typically refer to the people from this area as the “A-Group” culture, fertile farmland just south of the Third Cataract is known as the “pre-Kerma” culture in Upper Nubia, as they are the ancestors. The Neolithic people in the Nile Valley likely came from Sudan, as well as the Sahara, by the 5th millennium BC, the people who inhabited what is now called Nubia participated in the Neolithic revolution. Saharan rock reliefs depict scenes that have been thought to be suggestive of a cult, typical of those seen throughout parts of Eastern Africa. Megaliths discovered at Nabta Playa are early examples of what seems to be one of the worlds first astronomical devices, around 3500 BC, the second Nubian culture, termed the A-Group, arose. It was a contemporary of, and ethnically and culturally similar to. The A-Group people were engaged in trade with the Egyptians and this trade is testified archaeologically by large amounts of Egyptian commodities deposited in the graves of the A-Group people. The imports consisted of gold objects, copper tools, faience amulets and beads, seals, slate palettes, stone vessels, and a variety of pots. Around 3300 BC, there is evidence of a kingdom, as shown by the finds at Qustul. The Nubian culture may have contributed to the unification of the Nile Valley. The earliest known depiction of the crown is on a ceremonial incense burner from Cemetery at Qustul in Lower Nubia. New evidence from Abydos, however, particularly the excavation of Cemetery U, around the turn of the protodynastic period, Naqada, in its bid to conquer and unify the whole Nile Valley, seems to have conquered Ta-Seti and harmonized it with the Egyptian state

Water wheel
–
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel, with a number of blades or buckets arranged on the outside rim forming the driving surface. Most commonly, the wheel is mounted vertically on a horizontal axle, vertical wheels can transmit power either through the axle or via a ring gear and typically drive belts or gears, horizontal wheels usually directly drive their load. Water wheels were still in use well into the 20th century. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a wheel is called a mill race. The race bringing water from the pond to the water wheel is a headrace. In the mid to late 18th century John Smeatons scientific investigation of the water led to significant increases in efficiency supplying much needed power for the Industrial Revolution. Water wheels began being displaced by the smaller, less expensive and more efficient turbine, developed by Benoît Fourneyron, turbines are capable of handling high heads, or elevations, that exceed the capability of practical-sized waterwheels. The main difficulty of water wheels is their dependence on flowing water, modern hydroelectric dams can be viewed as the descendants of the water wheel, as they too take advantage of the movement of water downhill. The two main functions of water wheels were historically water-lifting for irrigation purposes and as a power source, when used for water-lifting power can be supplied by either human or animal force or by the water current itself. Water wheels come in two designs, either a vertical or a horizontal axle. The latter type can be subdivided, depending on where the hits the wheel. Engineers of the Hellenistic era Mediterranean region are credited with the development of the water wheel, Mediterranean engineers of the Hellenistic and Roman periods were also the first to use it for both irrigation and as a power source. The technological breakthrough occurred in the advanced and scientifically minded Hellenistic period between the 3rd and 1st centuries BCE. This is seen as an evolution of the paddle-driven water-lifting wheels that had appeared in ancient Egypt by the 4th century BCE. According to John Peter Oleson, both the wheel and the hydraulic Noria appeared in Egypt by the 4th century BCE. This is supported by finds at Faiyum, where the oldest archeological evidence of a water-wheel has been found
33.
Sakia
–
It is still used in India, Egypt and other parts of the Middle East, and in the Iberian Peninsula and the Balearic Islands. It may have invented in Hellenistic Egypt, Persia or India. The sakia was mainly used for irrigation, but not exclusively, as the example of Qusayr Amra shows, the sakia is a large hollow wheel, traditionally made of wood. One type has its clay pots or buckets attached directly to the periphery of the wheel, the modern version is normally made of galvanized sheet steel and consists of a series of scoops. The modern type dispenses the water near the hub rather than from the top and it is a method of irrigation frequently met within various parts of the Indian subcontinent. Sakia wheels range in diameter from two to five metres, though traditionally driven by draught animals, they are now increasingly attached to an engine. While animal-driven sakias can rotate at 2–4 rpm, motorised ones can make as much as 8–15 rpm, the improved modern versions are also known as zawaffa and jhallan. The historical Middle-Eastern device known in Arabic as saqiya usually had its buckets attached to a double chain and this allowed scooping water out of a much deeper well. An animal-driven sakia can raise water from 10–20 metres depth, and is considerably more efficient than a swape or shadoof, as it is known in Arabic. The terms referring to traditional as well as modern water-raising devices used in the Middle East, India, Spain, one clear distinction though is important. The term noria is used for devices using the power of moving water. For devices powered by animals, the term is sakia or saqiya. The term water-wheel is reserved, by definition, to wheels powered by flowing water, and should not be used for sakia wheels which are only lifting the water, other types of similar devices are grouped under the name of chain pumps. In Spain the term noria is used also for devices which are actually sakias. A sakia or saqiya differs from a noria in two substantial ways, first, by the way it is powered, namely by animal power or rarely by wind, in modern versions also by engines, but never by hydropower. The other difference is that a saqiya is lifting the water out of a well or a body of standing water, a noria in contrast uses the water power obtained from the flow of a river. The noria consists of a large, very narrow undershot water-wheel, in this it is very similar to the one type of sakia without a pot-garland, with the posts mounted directly on the wheel, thus the widespread confusion. A few historic norias were hybrids, consisting of waterwheels assisted secondarily by animal power, in Spanish an animal-driven sakia is named aceña, with the exception of the Cartagena area, where it is called a noria de sangre, or waterwheel of blood

Tamil Nadu
–
Tamil Nadu is one of the 29 states of India. Its capital and largest city is Chennai, Tamil Nadu lies in the southernmost part of the Indian Peninsula and is bordered by the union territory of Puducherry and the South Indian states of Kerala, Karnataka, and Andhra Pradesh. The state shares a border with the nation of Sri Lanka. Tamil Nadu is the eleventh-largest state in India by area and the sixth-most populous, the state was ranked sixth among states in India according to the Human Development Index in 2011, with the second-largest state economy after Maharashtra. Tamil Nadu is the second largest state economy in India with ₹13,842 billion in gross domestic product after Maharashtra. Tamil Nadu was ranked as one of the top seven developed states in India based on a Multidimensional Development Index in a 2013 report published by the Reserve Bank of India and its official language is Tamil, which is one of the longest-surviving classical languages in the world. Tamil Nadu is home to natural resources. In addition, its people have developed and continue classical arts, classical music, historic buildings and religious sites include Hindu temples of Tamil architecture, hill stations, beach resorts, multi-religious pilgrimage sites, and eight UNESCO World Heritage Sites. Archaeological evidence points to this area being one of the longest continuous habitations in the Indian peninsula, the ASI archaeologists have proposed that the script used at that site is very rudimentary Tamil Brahmi. Adichanallur has been announced as a site for further excavation. About 60 per cent of the epigraphical inscriptions found by the ASI in India are from Tamil Nadu. A Neolithic stone celt with the Indus script on it was discovered at Sembian-Kandiyur near Mayiladuthurai in Tamil Nadu, according to epigraphist Iravatham Mahadevan, this was the first datable artefact bearing the Indus script to be found in Tamil Nadu. Mahadevan claimed that the find was evidence of the use of the Harappan language, the date of the celt was estimated at between 1500 BCE and 2000 BCE. The early history of the people and rulers of Tamil Nadu is a topic in Tamil literary sources known as Sangam literature, numismatic, archaeological and literary sources corroborate that the Sangam period lasted for about six centuries, from 300 BC to AD300. Three dynasties, namely the Chera, Chola and Pandya, ruled the area of present-day Tamil Nadu, the Chera ruled the whole of present-day Kerala and parts of western Tamil Nadu comprising Coimbatore, Dharmapuri, Karur, Salem and Erode districts from the capital of Vanchi Muthur. The Chola dynasty ruled the northern and central parts of Tamil Nadu from their capital, Uraiyur, All three dynasties had extensive trade relationships with Rome, Greece, Egypt, Ceylon, Phoenicia, Arabia, Mesopotamia and Persia. Trade flourished in commodities such as spices, ivory, pearls, beads, Chera traded extensively from Muziris on the west coast, Chola from Arikamedu and Puhar and Pandya through Korkai port. A Greco-Roman trade and travel document, the Periplus of the Erythraean Sea gives a description of the Tamil country, besides these three dynasties, the Sangam era Tamilakam was also divided into various provinces named nadu, meaning country

Sub-Saharan Africa
–
Sub-Saharan Africa is, geographically, the area of the continent of Africa that lies south of the Sahara. According to the UN, it consists of all African countries that are fully or partially located south of the Sahara and it contrasts with North Africa, whose territories are part of the League of Arab states within the Arab world. Somalia, Djibouti, Comoros and Mauritania are geographically in Sub-Saharan Africa, the Sahel is the transitional zone between the Sahara and the tropical savanna and forest-savanna mosaic to the south. The Sahara pump theory explains how flora and fauna left Africa to penetrate the Middle East, African pluvial periods are associated with a wet Sahara phase during which larger lakes and more rivers existed. Geographers historically divided the region into several distinct ethnographic sections based on each areas respective inhabitants, commentators in Arabic in the medieval period used the general term bilâd as-sûdân for the vast Sudan region, or sometimes extending from the coast of West Africa to Western Sudan. Its equivalent in Southeast Africa was Zanj, which was situated in the vicinity of the Great Lakes region. The geographers drew an explicit distinction between the Sudan region and its analogue Zanj, from the area to their extreme east on the Red Sea coast in the Horn of Africa. In modern-day Ethiopia and Eritrea was Al-Habash or Abyssinia, which was inhabited by the Habash or Abyssinians, Sub-Saharan Africa has a wide variety of climate zones or biomes. South Africa and the Democratic Republic of the Congo in particular are considered Megadiverse countries, the Sahel shoots across all of Africa at a latitude of about 10° to 15° N. Countries that include parts of the Sahara Desert proper in their territories and parts of the Sahel in their southern region include Mauritania, Mali, Niger, Chad. The Sahel has a hot semi-arid climate, South of the Sahel, there is a belt of savanna, widening to include most of South Sudan and Ethiopia in the east. The Serengeti ecosystem is located in northwestern Tanzania and extends to southwestern Kenya, the Kalahari Basin includes the Kalahari Desert surrounded by a belt of semi-desert. The Bushveld is a tropical ecoregion of Southern Africa. The Karoo is a semi-desert in western South Africa and this occurred 10 million to 5 million years ago. By 3 million years ago several australopithecine hominid species had developed throughout southern, eastern and they were tool users rather than tool manufacturers. The tools were classed as Oldowan, roughly 1.8 million years ago, Homo ergaster first appeared in the fossil record in Africa. From Homo ergaster, Homo erectus evolved 1.5 million years ago, some of the earlier representatives of this species were small-brained and used primitive stone tools, much like H. habilis. The brain later grew in size, and H. erectus eventually developed a complex stone tool technology called the Acheulean

Niger River
–
The Niger River is the principal river of western Africa, extending about 4,180 km. Its drainage basin is 2,117,700 km2 in area and its source is in the Guinea Highlands in southeastern Guinea. The Niger is the third-longest river in Africa, exceeded only by the Nile and its main tributary is the Benue River. The Scottish explorer Mungo Park was the first Westerner known to have travelled to the portion of the Niger River. The earliest use of the name Niger for the river is by Leo Africanus in his Della descrittione dell’Africa et delle cose notabili che iui sono published in Italian in 1550, the name may come from Berber phrase ger-n-ger meaning river of rivers. As Timbuktu was the end of the principal Trans-Saharan trade route to the western Mediterranean. When European colonial powers began to send ships along the West coast of Africa in the 16th and 17th centuries, the Niger Delta, pouring into the Atlantic through mangrove swamps and thousands of distributaries along more than 160 kilometres, was thought to be no more than coastal wetlands. The Niger River is a clear river, carrying only a tenth as much sediment as the Nile because the Nigers headwaters lie in ancient rocks that provide little silt. Like the Nile, the Niger floods yearly, this begins in September, peaks in November, an unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. The result is a region of braided streams, marshes, and lakes the size of Belgium, the river loses nearly two-thirds of its potential flow in the Inner Delta between Ségou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, the average loss is estimated at 31 km3/year, but varies considerably between years. The river is joined by various tributaries, but also loses more water to evaporation. The quantity of water entering Nigeria measured in Yola was estimated at 25 km3/year before the 1980s, the most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria. The Niger takes one of the most unusual routes of any major river and this strange geography apparently came about because the Niger River is two ancient rivers joined together. Over time upstream erosion by the lower Niger resulted in capture of the upper Niger by the lower Niger. The northern part of the river, known as the Niger bend, is an important area because it is the major river and this made it the focal point of trade across the western Sahara, and the centre of the Sahelian kingdoms of Mali and Gao. The surrounding Niger River Basin is one of the distinct physiographic sections of the Sudan province, the origin of the rivers name remains unclear. What is clear is that Niger was an appellation applied in the Mediterranean world from at least the Classical era, when knowledge of the area by Europeans was slightly better than fable

Andes
–
The Andes or Andean Mountains are the longest continental mountain range in the world. They are a range of highlands along the western edge of South America. This range is about 7,000 km long, about 200 to 700 km wide, the Andes extend from north to south through seven South American countries, Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile. Along their length, the Andes are split into several ranges, the Andes are the location of several high plateaus – some of which host major cities, such as Quito, Bogotá, Arequipa, Medellín, Sucre, Mérida and La Paz. The Altiplano plateau is the worlds second-highest after the Tibetan plateau and these ranges are in turn grouped into three major divisions based on climate, the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes are the worlds highest mountain range outside of Asia, the highest mountain outside Asia, Mount Aconcagua, rises to an elevation of about 6,961 m above sea level. The peak of Chimborazo in the Ecuadorean Andes is farther from the Earths center than any other location on the Earths surface, the worlds highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to 6,893 m. The etymology of the word Andes has been debated, the majority consensus is that it derives from the Quechua word anti, which means east as in Antisuyu, one of the four regions of the Inca Empire. In the northern part of the Andes, the isolated Sierra Nevada de Santa Marta range is considered to be part of the Andes. The term cordillera comes from the Spanish word cordel, meaning rope, the Andes range is about 200 km wide throughout its length, except in the Bolivian flexure where it is about 640 kilometres wide. The Andes are the result of plate tectonics processes, caused by the subduction of oceanic crust beneath the South American plate. The main cause of the rise of the Andes is the compression of the rim of the South American Plate due to the subduction of the Nazca Plate. In the south, the Andes share a boundary with the former Patagonia Terrane. To the west, the Andes end at the Pacific Ocean, from a geographical approach, the Andes are considered to have their western boundaries marked by the appearance of coastal lowlands and a less rugged topography. The Andes Mountains also contain large quantities of iron ore located in mountains within the range. The Andean orogen has a series of bends or oroclines, the Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes Mountains at about 18° S. At this point the orientation of the Andes turns from Northwest in Peru to South in Chile, the Andean segment north and south of the orocline have been rotated 15° to 20° counter clockwise and clockwise respectively. The Bolivian Orocline area overlaps with the area of maximum width of the Altiplano Plateau, the specific point at 18° S where the coastline bends is known as the Arica Elbow

Peru
–
Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peruvian territory was home to ancient cultures spanning from the Norte Chico civilization in Caral, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty with its capital in Lima, ideas of political autonomy later spread throughout Spanish America and Peru gained its independence, which was formally proclaimed in 1821. After the battle of Ayacucho, three years after proclamation, Peru ensured its independence, subsequently, the country has undergone changes in government from oligarchic to democratic systems. Peru has gone through periods of political unrest and internal conflict as well as periods of stability, Peru is a representative democratic republic divided into 25 regions. It is a country with a high Human Development Index score. Its main economic activities include mining, manufacturing, agriculture and fishing, the Peruvian population, estimated at 31.2 million in 2015, is multiethnic, including Amerindians, Europeans, Africans and Asians. The main spoken language is Spanish, although a significant number of Peruvians speak Quechua or other native languages and this mixture of cultural traditions has resulted in a wide diversity of expressions in fields such as art, cuisine, literature, and music. The name of the country may be derived from Birú, the name of a ruler who lived near the Bay of San Miguel, Panama. When his possessions were visited by Spanish explorers in 1522, they were the southernmost part of the New World yet known to Europeans, thus, when Francisco Pizarro explored the regions farther south, they came to be designated Birú or Perú. An alternative history is provided by the contemporary writer Inca Garcilasco de la Vega, son of an Inca princess, the Spanish Crown gave the name legal status with the 1529 Capitulación de Toledo, which designated the newly encountered Inca Empire as the province of Peru. Under Spanish rule, the country adopted the denomination Viceroyalty of Peru, the earliest evidences of human presence in Peruvian territory have been dated to approximately 9,000 BC. Andean societies were based on agriculture, using such as irrigation and terracing, camelid husbandry. Organization relied on reciprocity and redistribution because these societies had no notion of market or money, the oldest known complex society in Peru, the Norte Chico civilization, flourished along the coast of the Pacific Ocean between 3,000 and 1,800 BC. These early developments were followed by archaeological cultures that developed mostly around the coastal, the Cupisnique culture which flourished from around 1000 to 200 BC along what is now Perus Pacific Coast was an example of early pre-Incan culture. The Chavín culture that developed from 1500 to 300 BC was probably more of a religious than a political phenomenon, on the coast, these included the civilizations of the Paracas, Nazca, Wari, and the more outstanding Chimu and Mochica. Their capital was at Chan Chan outside of modern-day Trujillo, in the 15th century, the Incas emerged as a powerful state which, in the span of a century, formed the largest empire in pre-Columbian America with their capital in Cusco

Radiocarbon dating
–
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed by Willard Libby in the late 1940s, Libby received the Nobel Prize for his work in 1960. The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with oxygen to form radioactive carbon dioxide. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died. The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained. Research has been ongoing since the 1960s to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the samples calendar age. Other corrections must be made to account for the proportion of 14C in different types of organisms, additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s. Conversely, nuclear testing increased the amount of 14C in the atmosphere, measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14C atoms in a sample. The development of dating has had a profound impact on archaeology. In addition to permitting more accurate dating within archaeological sites than previous methods, histories of archaeology often refer to its impact as the radiocarbon revolution. Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age, and they synthesized 14C using the laboratorys cyclotron accelerator and soon discovered that the atoms half-life was far longer than had been previously thought. This was followed by a prediction by Serge A. Korff, then employed at the Franklin Institute in Philadelphia and it had previously been thought that 14C would be more likely to be created by deuterons interacting with 13C. At some time during World War II, Willard Libby, who was then at Berkeley, learned of Korffs research, in 1945, Libby moved to the University of Chicago where he began his work on radiocarbon dating. He published a paper in 1946 in which he proposed that the carbon in living matter might include 14C as well as non-radioactive carbon, by contrast, methane created from petroleum showed no radiocarbon activity because of its age. The results were summarized in a paper in Science in 1947, Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages

The 4th millennium BC spans the years 4000 through 3000 BC. Some of the changes in human culture during this time included the beginning of the Bronze Age and the invention of writing. The city states of Sumer and the kingdom of Egypt were established, world population in the course of the millennium doubled, approximately from 7 to 14 million people. C.4000 BC—First neolithic settlers in the island of Thera, Greece, C.4000 BC—Beaker from Susa is made.

The cuneiform script proper emerges from pictographic proto-writing in the later 4th millennium, mesopotamias proto-literate period spans the 35th to 32nd centuries. The first documents written in the Sumerian language date to the 31st century. 3300–2900 BC—Construction of the Newgrange solar observatory/passage tomb in Ireland, 3300—Bronze Age starts in Indus Valley. C.3300 BC—Ötzi the Iceman dies near the border between Austria and Italy, only to be discovered in 1991 buried in a glacier of the Ötztal Alps. His cause of death is believed to be homicide, 3250–3000 BC—Construction of three megalithic temples at Tarxien, Malta. 3200–2500 BC—Construction of the Ħaġar Qim megalithic temple complex on Malta, C.3150 BC—Predynastic period ended in Ancient Egypt. The period includes 1st and 2nd Dynasties, C.3150 BC a lesser Tollmanns hypothetical bolide event may have occurred

New World
–
The New World is one of the names used for the Earths Western Hemisphere, specifically the Americas. The term was coined by Florentine explorer Amerigo Vespucci, the Americas were also referred to as the fourth part of the world. New World are meaningful in historical context and for the purpose of distinguishing the worlds major ecozones, and to classify plant and animal species that originated therein. One can speak of the New World in a context, e. g. when discussing the voyages of Christopher Columbus. For lack of alternatives, the term is still useful to those discussing issues that concern the Americas. The term New World is used in a context, when one speaks of Old World. Biological taxonomists often attach the New World label to groups of species that are exclusively in the Americas, to distinguish them from their counterparts in the Old World. New World monkeys, New World vultures, New World warblers, the label is also often used in agriculture. Common Old World crops, and domesticated animals did not exist in the Americas until they were introduced by contact in the 1490s. Other famous New World crops include the cashew, cocoa, rubber, sunflower, tobacco, and vanilla, there are rare instances of overlap, e. g. In wine terminology, New World has a different definition, Vespucci was finally convinced when he proceeded on his mapping expedition through 1501-02, covering the huge stretch of coast of eastern Brazil. But this opinion is false, and entirely opposed to the truth, Vespuccis letter was a publishing sensation in Europe, immediately reprinted in several other countries. The Venetian explorer Alvise Cadamosto had used the term un altro mundo to refer to sub-Saharan Africa, however, this was merely a literary flourish, not a suggestion of a new fourth part of the world. Cadamosto was quite aware sub-Saharan Africa was firmly part of the African continent, the Italian-born Spanish chronicler Peter Martyr dAnghiera often shares credit with Vespucci for designating the Americas as a new world. Peter Martyr used the term Orbe Novo in the title of his history of the discovery of the Americas as a whole, a year later, Peter Martyr again refers to the marvels of the New Globe and the Western hemisphere. Christopher Columbus touched the continent of South America in his 1498 third voyage, in another letter, Columbus refers to having reached a new heavens and world and that he had placed another world under the dominion of the Kings of Spain. The Vespucci passage above applied the New World label to merely the continental landmass of South America, although the proceedings of the Toro-Burgos conferences are missing, it is almost certain that Vespucci articulated his recent New World thesis to his fellow navigators there. In English usage the term New World was problematic and only accepted relatively late, while it became generally accepted after Vespucci that Columbuss discoveries were not Asia but a New World, the geographic relationship between the two continents was still unclear

5th millennium BC
–
The 5th millennium BC saw the spread of agriculture from Western Asia throughout Southern and Central Europe. Urban cultures in Mesopotamia and Anatolia flourished, developing the wheel, copper ornaments became more common, marking the beginning of the Chalcolithic. Animal husbandry spread throughout Eurasia, reaching China, world population grew slightly throughout the millennium, possibly from 5 to 7 million people

History of Iran
–
Iran is home to one of the worlds oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. Georg Wilhelm Friedrich Hegel names the Persians as the first Historical People, the Medes unified Iran as a nation and empire in 625 BC. It was the largest empire yet seen and the first world empire and they were succeeded by the Seleucid, Parthian and Sasanian Empires, who successively governed Iran for almost 1000 years and made Iran once again as a leading power in the world. Persias arch-rival was the Roman Empire and its successor, the Byzantine Empire, the Persian Empire proper begins in the Iron Age, following the influx of Iranian peoples. Iranian people gave rise to the Medes, the Achaemenid, Parthian, once a major empire of superpower proportions, having conquered far and wide, Iran has endured invasions too, by the Greeks, Arabs, Turks, and the Mongols. Iran has continually reasserted its national identity throughout the centuries and has developed as a political and cultural entity. The Muslim conquest of Persia ended the Sasanian Empire and was a point in Iranian history. Islamization of Iran took place during the eighth to tenth centuries, however, the achievements of the previous Persian civilizations were not lost, but were to a great extent absorbed by the new Islamic polity and civilization. Iran, with its history of early cultures and empires, had suffered particularly hard during the late Middle Ages. Many invasions of nomadic tribes, whose leaders became rulers in this country, the earliest archaeological artifacts in Iran were found in the Kashafrud and Ganj Par sites that are thought to date back to 100,000 years ago in the Middle Paleolithic. Mousterian stone tools made by Neandertals have also been found, in 1949, a Neanderthal radius was discovered by Carleton S. Coon in Bisitun Cave. Early agricultural communities such as Chogha Golan in 10,000 BC along with such as Chogha Bonut in 8000 BC, began to flourish in. Around about the time, the earliest-known clay vessels and modeled human and animal terracotta figurines were produced at Ganj Dareh. There are also 10, 000-year-old human and animal figurines from Tepe Sarab in Kermanshah Province among many ancient artifacts. The two main Neolithic Iranian settlements were the Zayandeh River Culture and Ganj Dareh, parts of what is modern-day northwestern Iran was part of the Kura–Araxes culture, that stretched up into the neighboring regions of the Caucasus and Anatolia. Susa is one of the settlements of Iran and the world. Based on C14 dating, the time of foundation of the city is as early as 4395 BC, the general perception among archeologists is that Susa was an extension of the Sumerian city state of Uruk. In its later history, Susa became the capital of Elam and it is one of the most artifact-rich archaeological sites in the Middle East
